  Comparison operators and logical operators that are used in a WHERE clause
  Rules of precedence for comparison and logical operators
  Use character string literals in the WHERE clause
  Write queries that contain an ORDER BY clause to sort the output of a SELECT statement
  Sort output in descending and ascending order
  4. Usage of Single-Row Functions to Customize Output
  Differences between single row and multiple row functions
  Manipulate strings with character function in the SELECT and WHERE clauses
  Manipulate numbers with the ROUND, TRUNC, and MOD functions

  5. Invoke Conversion Functions and Conditional Expressions
  Implicit and explicit data type conversion
  Use the TO_CHAR, TO_NUMBER, and TO_DATE conversion functions
  Nest multiple functions
  Apply the NVL, NULLIF, and COALESCE functions to data
  Use conditional IF THEN ELSE logic in a SELECT statement
  6. Aggregate Data Using the Group Functions
  Use the aggregation functions to produce meaningful reports
  Divide the retrieved data in groups by using the GROUP BY clause
  Exclude groups of data by using the HAVING clause
  7. Display Data from Multiple Tables Using Joins
  Write SELECT statements to access data from more than one table
  View data that generally does not meet a join condition by using outer joins
  Join a table to itself by using a self join
  8. Use Subqueries to Solve Queries
  Types of problems that subqueries can solve
  Subqueries
  Types of subqueries
  Write single-row and multiple-row subqueries
  9. The SET Operators
  SET operators
  Use a SET operator to combine multiple queries into a single query
